Description

First pic with my new ZWO Electronic Filter Wheel Mini. Changing filters will be much easier now. Now I can change filters and refocus with the electronic focuser without going outside in the backyard !

The image is noisy ; I will try to add subs later, especially Ha.

Lens opened at f/2.8. I have to rebuild an aperture mask to deal with the diffraction spikes.
